Pulmonary Embolism Pulmonary Microvascular Thrombosis or Both inCOVID-19?

摘要

An increased incidence of thrombotic complications has been described in COVID-19 patients,particularly in those with severe disease and/or admitted to the intensive care unit. Thecoagulation system is activated in the majority of patients, and d-dimer, a biomarkerof fibrin formation and degradation, also reflects true thrombotic disease.1–3 In addition, there is a strong association between d-dimer and chest computedtomography (CT) features suggesting pulmonary thrombosis.4
